Choosing the right CCTV system for your home is one of the most effective steps you can take to protect your family and property. With technology evolving rapidly, the options available in 2025 are better than ever — but the sheer choice can be overwhelming.
As professional CCTV installers across London, we've fitted hundreds of systems across properties of all sizes. This guide shares our honest, experience-based recommendations.

What to Look for in a Home CCTV System
Before comparing brands, understand the features that actually matter. Not every spec marketed by manufacturers adds genuine protection.
Resolution: 2K or 4K?
For most homes, 2K (4MP) is the sweet spot — clear facial identification at 10+ metres without burning through storage.
- 2K: Best for terraced, semis, and standard detached homes
- 4K: Worth it for long driveways, extensive grounds, or larger properties over 150m²
Night Vision
Most break-ins happen during darker hours. Modern cameras offer two types:
- Infrared (IR): Clear black-and-white footage up to 30m — best for sides and rear
- Colour night vision: Full-colour images using supplemental lighting — best for front-facing cameras
Remote Viewing
Non-negotiable in 2025. Every system we install includes:
- Live viewing from your phone, anywhere in the world
- Instant push notifications on motion detection
- Recorded footage playback directly from the app
Weatherproofing
London weather is unpredictable. Look for cameras rated IP67 or above — protection against rain, snow, dust, and temperature extremes. Every camera we supply meets this as minimum.

Key Takeaway
Wired vs Wireless CCTV
After installing both across hundreds of London properties, our view is clear: wired systems deliver superior reliability for permanent installations.
Wired Systems
Best for homeowners — install once, rely on it for years. No signal drops, no batteries to replace. Consistent HD/4K quality regardless of Wi-Fi load.
Wireless Systems
Better for renters or temporary setups. Easier to relocate but suffers from Wi-Fi interference, battery maintenance, and reduced reliability in poor weather.
Professional Installation vs DIY
DIY systems have improved, but professional installation ensures three things DIY can't guarantee:
Optimal Camera Positioning
We identify every blind spot and angle cameras for maximum facial identification range — something trial-and-error DIY mounting rarely achieves.
Weatherproof Cable Routing
Cables are routed through walls, soffits, and conduit. No exposed wiring that degrades in London weather or gets chewed by pests.
Network Configuration
Remote viewing, motion alerts, and multi-device access all configured correctly first time — with port forwarding, app setup, and security hardening.
